Slayer

The Slayer property is found on certain weapons, instruments, talismans, and spell books. This property will do the following when used in an offensive manner:

-Increases damage/success of all attacks on all monsters within that group.
-Slayer Weapons will do double damage to the monsters they are meant for.
-Slayer Spellbooks will cause most spells to do double damage to the monsters they are meant for.
-Slayer Instruments will increase your success chance by 20% when used on the creatures it is meant for.
-Slayer Instruments will decrease your success chance by 20% when used on the creatures from its opposing group.
-A successful use of a Slayer Weapon, Spellbook or Instrument will yield a little white flash on the monster

The Slayer property can be found as a rare drop in monster loot or crafted by a player when using a runic tool. Slayer instruments can only be found on monster loot. Slayer Spellbooks however can only be crafted by scribes using a scribe pen, and not necessarily a runic.

There are two types of slayers, Super Slayers and Lesser slayers. The Super Slayers cover large groups of racially similar creatures. There are seven different Super Slayers: Abyss Slayer, Arachnid Slayer, Elemental Slayer, Fey Slayer, Humanoid Slayer, Reptilian Slayer, and Undead Slayer. These super slayers cover a large group of different, but racially similar, monsters. The Lesser Slayers are creature specific. They will say the name of the creature then slayer. For example: "Lizardman Slayer".
